December 9 [16:00 EDT] -- Bill Berry may have retired from R.E.M., but he will be back behind the drum set this Saturday in his home town of Athens, Georgia for a benefit for the state chapter of the Tourette's Syndrome Association.

Berry has donated an autographed drum kit for a benefit auction and he'll play with Rick Fowler, a local musician who has Tourette's Syndrome, a neurological disorder that causes uncontrollable facial, body, and verbal tics and spasms.
